Incident Overview
A private tour aircraft diverted to Ohakea Air Force Base (AFB) after encountering deteriorating weather conditions en route. During the final approach, the crew selected full flaps, which resulted in the aircraft rolling left and right. The pilots were unable to maintain control, and the aircraft struck the runway surface before coming to rest. While all occupants escaped without injury, the aircraft sustained damage that rendered it beyond economical repair.
Aircraft Control Issues
The loss of control occurred when full flaps were deployed. The crew experienced an uncommanded roll motion, alternating left and right, which prevented them from stabilizing the aircraft for landing. The aircraft subsequently impacted the runway, coming to a stop on the runway surface.
Occupant Status
All occupants aboard the aircraft were uninjured in the incident.
Damage Assessment
Following the impact, the aircraft was evaluated and found to be damaged beyond repair. No further details on specific structural or system damage were provided.
Official Finding
The investigation identified a mechanical failure as the cause of the loss of control. Specifically, the port flap jack linkage eye-bolt failed, leading to an asymmetrical flap condition. This asymmetry made the aircraft uncontrollable during the landing flare.
